[CA] [CA11] What DSM do I need?

Adrobet,

The transducer appears to be a variant of the Airmar's P66 depth/speed/temp transducer. The tag which you have photographed is not the transducer's identification tag. Airmar attaches a white transducer tag to the plug end of the transducer. Like other Airmar transducers, the P66 was produced in a number of manufacturer specific variants designed to meet design criteria of corresponding fishfinder manufactures and models of fishfinders. The P66 is even produced in a version which is designed to support use with depth/speed/temperature instruments. Unfortunately, should you be unable to locate the aforementioned white tag, or should it have it been removed, then I would be unable to identify whether the transducer would be compatible with a DSM250, DSM30, or DSM300 ... the fishfinder sounder modules designed for use with C-Series Classic MFDs.
